One of the most prominent technology trends of the last two years has been the rapid emergence and evolution of new user interfaces using natural language, such as Alexa, Siri and Cortana. This trend will also have significant implications for IoT. This Research Note shares how improvements in cognitive computing, particularly Natural-Language Processing (NLP) has enabled technology service providers to design IoT solutions with improved microphone technologies as well as voice controlled interfaces to control and manage IoT applications. These enhancements ultimately lead to improved customer experiences.
